Mustafa invented a way of tapping this quantum effect via what's known as the dynamic Casimir effect. This uses a "moving mirror" cavity, where two very reflective very flat plates are held close together, and then moved slightly to interact with the quantum particle sea. It's horribly technical, but the end result is that Mustafa's use of shaped silicon plates similar to those used in solar power cells results in a net force being delivered. A force, of course, means a push or a pull and in space this equates to a drive or engine.
